The Allen-Bradley 1794-IA16 is a high-performance Discrete Input module from the Flex I/O family, designed to efficiently manage 16 non-isolated AC inputs. Engineered for DIN rail installation, this module interfaces seamlessly with electrical and signaling devices, and is compatible with various Flex I/O communication adapters such as ControlNet and Ethernet options. It operates on an input voltage range of 74-132VAC, featuring a nominal input voltage of 120VAC, with an emphasis on minimal wiring by employing terminal bases like the 1794-TB3 series for termination. With a power dissipation of 6.4 W at 132VAC and robust thermal management of 21.8 BTU/hr, the 1794-IA16 ensures reliable performance across a wide temperature range, accompanied by 16 yellow status indicators for real-time input channel monitoring.
